Introduction

PIPETMAN® G is a fully adjustable air-displacement,

pipette that is used with disposable tips. To meet

pipette user’s needs, PIPETMAN G relies on the

legendary accuracy, precision, and reliability of

PIPETMAN, with pipetting and purge forces dramatically

decreased for hours of comfortable pipetting.

Eight single channel models cover a volume range from

0.2 µL to 10 mL.

Eight multichannel models cover a volume range from

1 µL to 300 µL.

NOTICE

PIPETMAN G is identiﬁed by a visual blue ring.

Specifications

PIPETMAN G is a high quality pipette that offers

excellent accuracy and precision. The data provided in

the Maximum Permissible Errors table on page 4 were

obtained using PIPETMAN® DIAMOND Tips.

These values are guaranteed only when genuine

PIPETMAN DIAMOND Tips are used.

With a precise pipetting technique the P2G model

may be used to aspirate volumes as low as 0.1 µL

and the P10G model as low as 0.5 µL.

Setting the Volume

The volume of liquid to be aspirated is set using the

volumeter. The dials are colored either black or red to

indicate the position of the decimal point, depending on

the model (refer to Figure 3).

The volume is set by turning

the thumbwheel or the push

button (refer to Figure 4). The

push button makes it easier

and faster to set volumes,

especially when wearing

gloves. The thumbwheel may

be turned using only one hand

to slowly reach the required

setting.

To achieve maximum accuracy

when setting the volume,

proceed as follows:

●When decreasing the

volume setting, slowly

reach the required setting,

making sure to not

overshoot the mark.

●When increasing the

volume setting, pass the

required value by 1/3 of

a turn and then slowly

decrease to reach the

volume, making sure to

not overshoot the mark.

Fitting the Tips

To fit a new PIPETMAN DIAMOND Tip, push the tip holder

into the tip using a slight twisting motion to ensure a ﬁrm,

airtight seal.

PIPETMAN G is equipped with a stainless steel tip

ejector and can also be used with a plastic tip ejector,

available as an accessory. Refer to

PIPETMAN G User’s

Guide LT801122,

ACCESSORIES.

Fitting the Tips on P2G and P10G Models

NOTE

For the P2G and P10G models, a dual-position

adapter (plastic) is required to ﬁt DL10 tips

(longtips) or D10 tips (short tips). The metallic rod

of the tip ejector is shaped so the adapter may be

clipped to it in either position.

P2G and P10G models are delivered

with the adapter in place, ready to

use DL10 tips. If D10 tips are used, the

adapter must be repositioned in the

shorter slot as follows:

1. Pull the adapter down from the

metallic rod.

2. Turn the adapter 180°.

3. Reﬁt the adapter so the end

of the metallic rod engages the

shorter slot of the adapter.

NOTE

Plastic tip ejectors can be

used and ordered separately

(refer to

PIPETMAN G User’s

Guide LT801122

Pre-Wetting the Tips

Pre-wetting the tips before pipetting helps prepare the

tips for the best pipetting performance. Ideally, the pre-

wet includes both immersing the tip in the liquid and

performing one pipetting step.

Pre-wetting the tips helps ensure that volumes that

you pipette will achieve accuracy and precision within

specifications.

Ejector Spacer for PIPETMAN G 10 µL

Multichannel Models

According to the tip used, D10 or DL10, you may have to

exchange the ejector spacer. The broadly spaced one is

for D10, and the narrowly spaced one is for DL10.

1. Remove the tip ejector, keeping both ejector locks

depressed. Pull the tip ejector down.

2. Gently press the tabs from the ejector spacer and

remove it from the tip ejector.

3. Insert the alternative

ejector spacer and click

it to the tip ejector.

4. To refit the tip ejector,

gently re-insert the tip

ejector vertically into the

rails of the ejector

support.

Aspirating

1. Press the push button to the ﬁrst stop

(this corresponds to the set volume of liquid).

2. Hold the pipette vertically and immerse the tip

in the liquid (refer to

PIPETMAN G User’s Guide

LT80112 2)

3. Release the push button slowly and smoothly (to

the top position) to aspirate the set volume of

liquid.

4. Wait one second, and then withdraw the pipette

tip from the liquid. You may wipe any droplets

away from the outside of the tip using a medical

wipe; however if you do so, take care to avoid

touching the tip’s orifice.

First stop

Second stop

Dispensing

1. Place the end of the tip against the inside wall of the

recipient vessel (at an angle of 10° to 40°).

2. Press the push button slowly and smoothly to the

first stop.

3. Wait for at least one second, then press the push

button to the second stop to expel any residual

liquid from the tip. Keep the push button pressed

fully down and (while removing the pipette) draw

the tip along the inside surface of the vessel.

4. Release the push button smoothly. Eject the tip by

pressing firmly on the tip ejector button.

It is recommended to regularly verify the volume

displayed on the dial while pipetting.

Maintenance

Routine maintenance will help keep your pipette in

good condition, ensuring a continued high level of

performance. Maintenance is limited to cleaning or

autoclaving the parts speciﬁed in the

PIPETMAN G

User’s Guide

LT801122, or to replacing the push button,

connecting nut, tip ejector, tip holder, seal, and O-ring.

NOTICE

PIPETMAN P2G and P10G should not be

disassembled. You may only replace the

push button, tip ejector, and its dual-position

adapter. With these pipettes, if the tip holder

is damaged, the piston may also be damaged.

After replacing any parts, you should verify

the performance of your pipette following the

veriﬁcation procedure available on the Gilson

website (www.gilson.com). If the pipette needs

to be readjusted, please contact your local

authorized Gilson Service Center.

NOTICE

Decreased pipetting forces are due to the

design of the piston assembly, which includes

a very high-quality lubricant (part number

5440011070). The use of any other lubricant

voids the warranty of this pipette.

10 QUICK GUIDE | PIPETMAN® G

Warranty
